Concrete Protection

More than just a topical coating, Seal Saint Louis' concrete sealant penetrates below the surface of the concrete and reacts instantly with the alkali to form a silica gel membrane on the surface of the voids and particulate, immediately starting to waterproof the substrate.

Over 3 to 7 days the silica gel membrane hydrates hardening in to a solid, yet breathing, internal membrane, providing a permanent seal and moisture barrier, as well as increased surface hardness. It will all so protect your concrete from freeze-thaw cycles, salt and chemical attack, the benefits are PERMANENT.
